[texts]Information Retrieval: A survey - Ed Greengrass
Information Retrieval (IR) is the discipline that deals with retrieval of unstructured data, especially textual documents, in response to a query or topic statement, which may itself be unstructured, e.g., a sentence or even another document, or which may be structured, e.g., a boolean expression. The need for effective methods of automated IR has grown in importance because of the tremendous explosion in the amount of unstructured data, both internal, corporate document collections, and the imm...

[texts]Uppbyggnad av lexikonbas för en datorbaserad innehållsanalys av intervjutext - Inger Bierschenk
This report is part of a project on content analysis and deals with dictionary construction as basis for statistical analyses of interviews. The generation of lexical data bases consisting of nouns, adjectives and verbs is described and results from experimentation on authentic materials are accounted for. Dictionaries of scaled base forms of adjectives and verbs are compared with truncated items. The purpose is to obtain a perfect match, so that the results can be assigned a scale value for the...

With growing amounts of research data it becomes increasingly difficult to handle and maintain them and also get an overview over their structure. When a research project has been going for some years, various types of materials have been collected and stored in various ways and at different places. The purpose of this document is to describe how the body of records of a research project at a Swedish research department during the years 1972-1977 has been organized for the archives...

[texts]Semantic Similarity Using Web Search Engine - Meghana Raut, Nityaspandana Nalamari, Darshana Rane
Measuring the semantic similarity between words is an important component in various tasks on the web such as relationextraction, document clustering, and automatic metadata extraction. Despite the usefulness of semantic similarity measures in theseapplications, accurately measuring semantic similarity between two words (or entities) is still difficult. We propose a method to estimatesemantic similarity using page counts and text snippets retrieved from a web search engine for two words...

Response time as defined for this study is the time that it takes for all files that constitute a single webpage to travel across the Internet from a Web server to the end user's browser. In this study, the authors tested response times on queries for identical items in five different library catalogs, one of them a next-generation(NextGen) catalog. The authors also discuss acceptable response time and how it may affect the discovery process...

[texts]CuInS2 Films Deposited by Aerosol-Assisted Chemical Vapor Deposition Using Ternary Single-Source Precursors - Jin, Michael
Polycrystalline CuInS2 films were deposited by aerosol-assisted chemical vapor deposition using both solid and liquid ternary single-source precursors (SSPs) which were prepared in-house. Films with either (112) or (204/220) preferred orientation, had a chalcopyrite structure, and (112)-oriented films contained more copper than (204/220)-oriented films. The preferred orientation of the film is likely related to the decomposition and reaction kinetics associated with the molecular structure of th...

Discoverability is a popular buzzword—ultimately meaning the degree to which scholars can locate the content needed to advance their research and other creative activity. Improved user discovery experiences require heightened collaboration among (1) scholarly publishers and their published authors; (2) search engine developers, database providers, abstracting and indexing services, and academic publishers; (3) electronic resource management and integrated library system vendors; and (4) librar...

[texts]On the structure of gaseous confined laminar diffusion flames: Numerical investigation - Mawid, M. A.
The structure and characteristics of gaseous confined laminar diffusion flames are investigated by numerically solving the time-dependent two-dimensional axisymmetric conservation equations. The numerical model accounts for the important chemical and physical processes involved, including axial diffusion, viscous effects, radial convection, and finite-rate chemistry. The numerical results clearly show that the flame has a finite thickness and leakage of fuel vapor into the flame zone is possible...

Reference to available Apollo photographs is included in the appendix, which also includes information on ordering orb...
